Two young brothers suffocated in a linen chest, where they were found by their parents Wednesday morning, authorities said.

The parents woke up, couldn't initially find Anthony Leydig, 5, and 3-year-old Alyjah and began looking for them. State police said the chest in an upstairs bedroom had a combination lock that could have latched if the boys climbed inside.

Police said the boys were last seen around 10 p.m. before the parents went to bed.

No charges have been filed in the deaths.

The couple, Nathan Leydig (search) and Heather Baker, also have a 6-year-old son, police said.
